发动机凸轮轴优化设计

Optimum design of engine camshaft

提高汽车燃油经济性的方法有很多,减轻发动机重量是其中重要的一种解决方法。文章基于动力学分析,在保证凸轮轴平稳性、耐磨性、抗扭强度以及其本身的使用性能的条件下,对发动机关键部位凸轮轴进行结构优化,最终实现了发动机的轻量化、低成本以及节能环保的目的。经试验验证,优化后的凸轮轴有效地提高了发动机的质量功率比。

There are many ways to improve vehicle fuel economy, and reducing engine weight is one of the most important solutions. This article is based on dynamics analysis, optimize the structure of camshaft under the condition of ensuring the stability of cam shaft, wear resistance, torsional strength and its performance, and finally realize lightweight, low cost, energy saving and environmental protection of the engine. The experimental results show that the optimized camshaft effectively improves the ratio of mass and power of the engine.
